How will we get to Mars by 2046?
I'm no lawyer, I don't only ask questions I already know the answers to. But the Mars question appeals to me, because we've already explored all the places to explore here on Earth, and we've already walked the Moon. Mars is a lot farther, but so what? Since when has the seemingly impossible stopped us? If I had any building skills, I'd build a rocket ship out of spare parts from the 50s, and power it with an atomic V8. Or I'd figure out how to fold the universe so Mars would only be one small step away. How would you do it?
